slang term for marijuana, originated in eastern MA. the celtics symbol, a green clover, is somewhat similar to the marijuana leaf, so there... when making a deal for some green, you say you want some celtics tix, the dealers then says a row number (price) and seat (amount in grams or fractions of an ounce, you decide)
Johnny Pothead: Hey man, I need some celtics tix. U got any??
Carlos Sanchez: Sure, manggg. I got tix for row 60 seat 3.
Oblivious Mother: Hey Craig! I've got some celtics tickets for tonight, you wanna go?
Closet Green User: Teehee, sure mom! LOLZ!
Celtics Coach Doc Rivers: Well, here you go Paul Pierce, here's all the celtics tickets you ordered....
Celtics Captain Paul Pierce: No, dumbass! Not THOSE celtics tickets!!
